' and cooperating with a iish-plate or analogous device.

The primary obj ect of the invention is to provide a simple and eHective means forsecuring a series of nuts by the application thereto 'of a plate or elongated locking member, which is formed with a series of openings or slots toreceive the nuts after the latter have been turned or secured against a fishplate, and toprevent removal of the lockingplate by securely attaching the same to the fish-plate in such a manner that a ready separation can be pursued when desired.

In the drawings, Figure 1 illustrates a top plan view of a railroad-rail joint, showing a {ish-plate attached thereto and a lockingplate engaging the nuts and embodying the features of the invention. Fig. 2 is a side elevation of the same. Fig. 3 is a detail perspective view of one end of the locking-plate and fish-plate, showing a nut and a portion of l a bolt arranged in operative relation thereto.

Similar numerals of reference are employed to indicate corresponding parts in the several views.

The numeral 1 designates rail-sections Which are assembled inthe usual manner for joint purposes and provided with suitable openings to receive headed bolts 2 with screw-threaded terminals, to which nuts 3 are applied and turned up close to aiish-plate' 4 and secured against accidental loosening movement by a locking-plate 5.

The essential features of the invention reside inthe fish-plate i and locking-plate 5, both plates being continuous with respect to `the joint formed by the meeting ends of the rail-sections. The iish-plate 4 has at each end an outwardly-projecting angular offset or shoulder 6v with .a key-opening 7 therethrough. The locking-plate 5 at each eX- tremity has a corresponding angular end 8, with an opening 9 t erein to coincide with the opening 7 the angular end 8 of the lock- Specification of Letters Patent.

angular oifset or shoulder 6 of the fish-plate The locking-plate 5 is securedby a split ing-plate 5 being closely fitted against the spring-key 10, inserted through the openings -9 and 7, with the head thereof located against V the inner side of the angularl end 8 of the locking-plate and the ends of the legs outturned or separated, as at 11, adjacent to the outer surface of the offset or shoulder 6 of the fishplate. The locking-plate 5 has a plurality of slots 12 formed therein, which may be square or polygonal, in accordance with the shape of the nuts 3, said slots 12 preferably opening through the bottom edge ofthe locking-plate 5 to permit the latter to be easily set over the nuts 3 after said nuts have been tightly secured against the iish-plate. It will be seen that when thelocking-plate 5 is applied to the nuts 3 and secured at opposite terminals to the offsets or shoulders 6 of the fish-plate it will be impossible for the nuts to accidentally work loose or to move in view of vibration or pound ofthe rolling-stock on the rails but when desired to repair the rails or substitute Others for those that may have becomeworn and unt for further use the split keys 10 may be readily removed and the locking-plate 5 detached to permit the nuts 3 to be run off the bolts 2.

The improved nut-lock is very simple in its mately related, and said shoulders ofthe ishplate and the angular end of the lockingplate may be formed at the time of preparing the two plates or may be employed with similarr plates now in use by welding or riveting operations.

Having thus described the invention, what is claimed as new is# 1. The combination with a railroad-rail joint, and bolts and nuts therefor, of a fishplate having outwardly-projecting end shoulders, a locking-plate having openings therein to fit over the nuts and angular terminals to snugly bearl against-the inner portions of the shoulders of the fish-plate, and removable keys inserted through the angular terminals IOO inserted through the coinciding openings at the ends of the twoy plates, the heads of the keys being disposed inwardly against the angular terminals of the locking-plate and the ends thereof spread apart adjacent to the outer surfaces of the shoulders of the iisliplate.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
